What Are Closed Captions? A Complete Guide to Meaning, Benefits & Examples

This guide explains the closed meaning, how closed captioning works, the benefits, USA rules and real examples. It also shows how to switch captions on.

What Are Closed Captions? Meaning and How They Work

Closed turn sound into text. They help people follow a video when they cannot hear it well, or at all.

What does closed mean? The word “closed” means the text stays hidden until a viewer turns it on. Captions show speech and also non-speech sounds, like a door slam or a phone buzz. They often name the speaker too.

What is the difference between open and closed? Open captions are burned into the video. Nobody can turn them off. this sit in a separate track, so viewers can switch them on, off or change their look.

What is the difference between this captions and subtitles? In the USA, captions and subtitles are not the same thing. Captions show dialogue plus sounds, mainly for Deaf and hard of hearing viewers. Subtitles assume you can hear but may not know the language, so they mostly show speech or a translation. Many streaming apps use the label SDH (subtitles for the deaf and hard of hearing) for caption-style text. The UK and many other countries use “subtitles” for both.

How do we work on this? There are two main ways to make them:

• Pre-recorded captioning: A captioner types the text, times it and checks it before the video airs.
• Live captioning: A trained stenographer or a respeaker types or repeats speech as it happens. Some systems use speech recognition and AI. Live captions often lag by a few seconds.

Captions also show up in two styles. Pop-on captions appear as a full block of text. Roll-up captions scroll line by line, which suits live news and sports.

Behind the scenes, old analog TV carried captions on Line 21 using the EIA-608 standard. Digital TV uses CEA-708, which allows more fonts, colors and languages. Online, creators often upload caption files such as SRT.

When were closed captions invented? Closed captioning was first shown in the USA in December 1971. PBS and WGBH helped test it. Regular captioned shows began on American TV on March 16, 1980. The National Captioning Institute (NCI) was set up in 1979 to work with the TV networks. You can read more in this overview of closed captioning.
